MIXING-VALVE.

v Specification of Letters Patent.

Patented lieen, 1913.

pplicaton led September 14:, 191'2. Sera1No. 720,326.

To all whom it may concern Be itknown that I, RICHARD' .0. A. HOLZ- neusniv, a citizen of the United States of America, a resident ofthe borough of Bronx,A Westchester county, State of New 'Yorka have invented' certain new and useful Improvements in h/liXin. ;-Valves7 of which the following is a specication.

This invention relates to improvements Vin niXing valves with particular reference to the mixing of hot and cold water for use 1n bath rooms. and similar places. My 1nvention7 however, is not limited in itsuse to the mixing of water, but is usable and may be applied for the mixing of other liquids. f

.One object. of the invention is to provide a mixingvalve of simple construction containing several novel features for the safe and sure operation of the various parts with a view of equalizing the wear thereof to increase the life of the' valve.

Another Objectis to eliminate the use of a stuthng box around the operating handle of the valve. I

Still another object is to provide a con struction embodying balls as the closing elements ofthe inlet valves which 'greatly facilitate the automatic closing thereof.

`Still other objects 'o' the invention will appear as the specification proceeds.

lshowing the configuration of the cams, and

' Fig. 8 shows certain features of my invent-ion embodied in a faucet.,

In the' drawings the reference numeral 8 represents the vvalve casing which may be` of any suitableor convenient form. In the present instance I have illustrated 'the cas-4 ing as being circular and provided with a vseat 9 and lugs 10 for the reception of screws l1 for securing the cover 12. The cover is provided with .a depending circular flange formin 'a seat' 1:3 adapted to en ge the aforesaid seat 9 whereby a. watertlght clpliquid.

sure' of the valveca'sing'is obtained without` 'i the' use of a packing. The ca'sing yis pro vided with an outletll andv twoinletslo,

.15 which receive the inlet valves, of which only one need Ato be described as. they are alike. i

16 represents a valve body or sleeve threaded into the inlet openings as shown and to" which the vinlet pipe 17 is attached by means of a coupling 18. 1 A' l mixing chamber .21l within the Casin 8 through several smaller openings 22. @he valve opening 20 is closed by which rests on the valve seat 24.

is a spring contained within a pocket 26 lfor forcing the Vball against theseat 24 toclose the valve. The pocket 26 is suitably se. ,curedwithin the sleeve 16 by three or more small lugs 27 at the top only one lug being shown, leaving openings 28 for the flow of the liquid. A follower is interposed between.

the ball 23 andthe spring 25.

30 isa plunger for opening the valve by forcing the ball against the spring 25 and the bait 2a compressing the'l'atter.l rlhe plunger is pro-,

vided with spaced feet B1 which engage the ball and form spaces for'. the flow of the It is lfurtherprovided with' stops 32lixniting its upward oroutward movement as will be understod.

.33 is a shoulder 'on lthe plunger'BO.- the two shoulders 33 on, the two lplungers 30 rests the valve actuating member '34 which is provided with slots 35 to permit of play .between the member 34 and the plungers 30. Th'evalve actuating member 34- further carries cams 36, 37 and38 "'circ`u'm ferentially disposed around the center aperture 3S) and other cams 40, 40, also circumferentially arranged but nearer the center ofthe member 34. l 4l and 42, 42 represent armsof a spider secured to the operating stern '43., -The arm 4l and the arms 42 carry cam rolls 50, 51; 5I. The operating stem is recessed at 44 to receive a spring -t and a ball i6 which operating stem is provided 'with a grplmd, seat 4S which engages a seat 49 on; the cover 12. By this construction a water'i'ffht closure `is obtainedbetween the Opeifafng stem and the cover without the use elfe..

packing.

' latter rests on a post 47 in the casing 8.1;;.Tbe

es 19 1s the valve seat member having the central opening 2'() communicating with the tive in that jthey move within Vthe 4circle of lormally tlieLhandle'stands in shut-off position as shown. in Fig. 5 and the spider arlns are ina Acorresponding inactive position as shown in'Fg., l. Whenit is desiredto turn on thev cold water, the operat- -ing stein turned into the position illusi 4tratedin Fig. where it will be seen that the arm il hasbeen turned to cause the 'cani roll `50 to ride. up on the cam' .38 which ca-us'es-t11e member 3l to be depressed on that' side'- against the shoulder 33 .on the plunger which of course opens the valve 'to let the cold water flow into 'the chamber y 21 and out through the, outlet 14'. When .p hot water is-wanted the spider is turned',

into the position shown in Fig. 4 when' the cam roll v engages ca1n 36 and the member '34 is depressed oppositely to the position shown in Fig. 2. In both, of these cases it will be seen, that the' cam rolls 5l are inacthe cams 3S' and.

Whenmixed Water is Wanted the spider isv turned into the position. illustrated 1n Fig. 3 4Where itl is seen that the camrroll 5,0 en- 'gages'cam 37 and the cam rolls 51 engage .the 'cams l0 thus causing an even downward depression of vthe member. 34:. to' ope'uboth inletvalves at once so that both hot and cold".

Watetenter the .mixing chamber 21 and pass outthrough the outlet 14. v y

When it is desired to adjust-the temperature-of the 'mixed Water, it may be done by t-nr'ning'fthe handle on the operating stem -13 a little to the right or the left asithe case may be. To this end .the cams 40 may be formed as shown in Fig. 7 in which it' -will be seen that-they are each' provided with a high porticn'SO lso thatl if therolls 51 are turned as shown in Fig. 7, the cam tol the' lef-t will be' depressed more than the right'cam, consequently the' left side of the actuating member 34 will be depressedl morethan the' right side which ivillpermit the cold Water inlet 'valve to close slightly to decreasethe flow, hence the temperature of the mixed Water wilLrise. If the cam rolls 51 are moved a little totheleft, the Warm Water flow will be retarded and the tempera.

ture of the mixed water will be lokvered.

'Suitable directions may be placed on the cover tol indicate the operations :for temper.-

ing 'the water and as illustrated in Fig. 5.

It 'will be observed that the principle of vmitted through the inlet valves, or for the purpose of adpistmg the temperature of the' mixed. Water. Again it vvill `be seen, that described, pounding-v normally the valves are closed by the combmed action of the springs 25,- and the pressure of the liquid on the balls 23 and as the member rests on the valve plungers it is kept at .its normal level by theA pressure which tendsl to fclose the valves.' One ativanon the various parts, particularly -on the cam vrolls and" thev V actuatingvr member- `34, l

which are disengaged normallyri Further, the

A"tage of this construction is a saving in wear cams may easily befso `shaped as to furnish 4, very little resistance to thejengagement of 'l the .cams by the cam'rolls,therebypreventing" suddenblows or' shocks' tothe device; As shown-in \Fig. 6'the outer cams may be depressed :1t-5 5 t .provide avnatijiral' stopping vposition for* the cam 'roll andllto-prevent the. latter4 'om'4 leaving the camsfof themselves. ,'The''ajm rolls 'mayg'also be 'knurled as shown. 5 I havefa-Isojfound by bis actual operation that4 by "the`I construction o1 hammering of the :Water isI eliminate By the use of al'ball to close the valve. a certain closure isobtained and the cost down.

have; showin -my invention'` applied toa faucet.4 4In this, instance 60 represent-s the body, 61 the valve seat memberv 1 while 62 is a stuing box; The aperture 63' is clo'sedvby'a ball 64'under'tens1onby the v spring 65. A follower 66 may beprovided bet-Ween the, ball and the'spri-ng if desired,v

The ball en ages the scat 67. Inthis instance4 the p nger 68 is integral with the 'structed as' above described.' The stem is threaded at' ZO-into the valve's'eat memberV 61. When the Aste'mis screwed inwardly the ball is forced back from its seat and Water passes. from Athe supply pipe '71v past I.the

spring pocket 72, through the .opening'63,l

past thelunger 68 vand outthrough the' outlet. 73. en the stem is screwed outwardly the ball `follows the plunger until the spring forces it onto the seat 67 and the valve is closed. rlhis construction avoids the usual trouble with leaky` faucets d ue to Worn washers and the luke and avoids the Well 'known pouhding and irregular flow of the Water, because in this instance the solid stream of Water is divided Ias it passes' around the pocket member'past theball.

Many details 1n the constructionof my invention may of course be made Without departing from the' spirit thereof ,and within the scope ofl the appended claims.
